100Base-T (IEEE 802.3u) Fast Ethernet

A networking standard that supports data transfer rates up to 100 Mbps (100 megabits per second). 100BASE-T is based on the older Ethernet standard. Because it is 10 times faster than Ethernet, it is often referred to as Fast Ethernet. Officially, the 100BASE-T standard is IEEE 802.3u.

Like Ethernet, 100BASE-T is based on the CSMA/CDLAN access method. There are several different cabling schemes that can be used with 100BASE-T, including:

  • 100BASE-TX: two pairs of high-quality twisted-pair wires
  • 100BASE-T4:four pairs of normal-quality twisted-pair wires
  • 100BASE-FX: fiber optic cables
  • Also see the Ethernet Designations chart in the Quick Referencesection of Webopedia.
